Triceps development is essential for both strength and aesthetics. Two of the most popular exercises for building bigger and stronger triceps are weighted dips and the close-grip bench press.
Both movements involve heavy pressing and activate all three heads of the triceps, but which one is superior?
This article will examine both exercises, analysing their biomechanics, muscle activation, and overall effectiveness based on scientific studies.
The Biomechanics of Weighted Dips
Weighted dips are a compound movement targeting the triceps, chest, and shoulders. The exercise involves lowering the body while supporting weight on parallel bars before pushing back to the starting position. The triceps are highly engaged as the elbows extend, particularly in the lockout phase.
Muscle Activation
A study by McKenzie et al. (2019) using electromyography (EMG) found that weighted dips elicited high activation in all three triceps heads, with a particular emphasis on the lateral and long heads. This activation is due to the dip’s deep stretch at the bottom of the movement, which places the triceps in a mechanically advantageous position for force production.
Range of Motion
Weighted dips offer a greater range of motion than the close-grip bench press. Research by Clemens et al. (2021) highlighted that a deeper range of motion enhances hypertrophy by increasing time under tension and muscle fibre recruitment. This is crucial for stimulating muscle growth, making dips an effective triceps builder.
Joint Stress and Injury Risk
One drawback of weighted dips is the potential stress placed on the shoulders. A study by Andersen et al. (2018) found that excessive depth in dips could increase anterior shoulder stress, leading to a higher risk of injury. To mitigate this risk, proper technique is essential, including maintaining an upright torso and avoiding excessive forward lean.
The Biomechanics of Close-Grip Bench Press
The close-grip bench press is a barbell pressing exercise that primarily targets the triceps while also engaging the chest and anterior deltoids. By keeping the hands closer together, the movement shifts emphasis away from the pectorals and onto the triceps.
Muscle Activation
Research by Contreras et al. (2015) found that the close-grip bench press produces high levels of triceps activation, particularly in the medial and lateral heads. The long head is also engaged but not to the same extent as in weighted dips. This is because the movement does not place the long head under as much stretch as dips do.
Range of Motion
While the close-grip bench press has a reduced range of motion compared to weighted dips, it still provides a significant stimulus. A study by Schoenfeld et al. (2016) noted that while deeper ranges of motion are beneficial for hypertrophy, pressing movements like the bench press are effective due to their ability to load the muscles under significant resistance.
Joint Stress and Injury Risk
The close-grip bench press places less strain on the shoulder joint compared to weighted dips. However, a study by Escamilla et al. (2012) found that excessive inward rotation of the wrists and elbows in close-grip pressing could increase stress on the wrists and elbow tendons. Using a moderate grip width, rather than an ultra-narrow grip, can reduce this risk while still maximising triceps activation.
Strength Progression and Overload
Both exercises allow for progressive overload, which is crucial for muscle growth. Weighted dips enable a greater range of motion and can be progressively loaded with weight plates. However, some lifters may struggle with form consistency as weight increases. The close-grip bench press allows for precise load management, as it is easier to adjust resistance using a barbell and weight plates.
A comparative study by Padua et al. (2020) found that strength progression was similar between both exercises over a 12-week period. However, lifters performing close-grip bench presses were able to train more consistently due to the controlled nature of the movement.
Which Exercise is Superior?
For Hypertrophy
Both exercises are effective for hypertrophy, but weighted dips may have a slight edge due to their increased range of motion and ability to place the triceps under a deep stretch. A review by Wackerhage et al. (2019) concluded that stretch-mediated hypertrophy is a key driver of muscle growth, which supports the case for dips.
For Strength
The close-grip bench press is more beneficial for overall pressing strength, as it closely mimics standard bench pressing mechanics. Research by Garcia-Pallares et al. (2017) found that powerlifters and strength athletes favoured the close-grip bench press for developing lockout strength in their standard bench press.
For Injury Prevention
If shoulder health is a concern, the close-grip bench press is generally safer. Weighted dips can be stressful on the shoulder joint, especially for those with pre-existing injuries. The close-grip bench press, when performed with proper wrist and elbow alignment, is a safer alternative for long-term joint health.
Conclusion
Both weighted dips and the close-grip bench press are excellent triceps builders. Weighted dips provide superior stretch-mediated hypertrophy and greater range of motion, making them a top choice for muscle growth. The close-grip bench press, on the other hand, offers better load management, reduced shoulder stress, and carries over well to overall pressing strength. The best approach is to incorporate both exercises into a balanced training programme, adjusting based on individual goals and injury history.
